Make single-serving coffee systems greener with ReFill Cup Reusable Coffee K-Cups for Keurig 2.0 and 1.0 Brewers. While single-cup machines are incredibly convenient, they can be costly and generate far more waste than traditional electric coffee making systems. K-Cups and similar products can only be used once before they're thrown away, winding up in landfills or the ocean where they can harm wildlife and take decades to biodegrade. With the ReFill Cup filter, you can still enjoy single-cup convenience without incurring the high costs of disposable cups or generating excessive waste. The filter is the same size as disposable K-Cups, making it easy to use your preferred blend. When your drink is brewed, you simply remove the filter from your brew system, wash it out and store it away for next time. The versatile reusable coffee filter can be used with 1.0 and 2.0 Keurig Brewing Systems, for added convenience.
